Because of an extreme fire risk in the reserve due to persistent drought, Mr. Marshall, an expert in fire fighting, arrives to lend a hand. When Marshall meets Toomai's elephant Kala Nag, the animal reacts full of joy and confidence. Marshall tells him that he knew Kala Nag's father well. Shortly thereafter, Bergen and a few of his men are trapped by a huge fire - and now they need help from Marshall and Kala Nag.
